Subject: AMBER: Is there any way to extract one frame from a whole trajectory just saving one file by using ptraj

Dear amber users,
I'm using ptraj and I would like to extract a restart file from a
trajectory.
I know is the frame 92, so one way is going to the corresponding
trajectory file of the molecular dynamics by dividing the
number of frames collected in each trajectory file (20) and giving
as input just it.
But for example if I would like to process the whole trajectory
(Coordinate processing will occur on 441 frames),
Is there anyway to specify to ptraj that I want just to extract
the frame 92 after read all the frames without having to save
anything else?,
Thank you,
JJ
